When all three external providers (Stripe, Sift, MaxMind) return errors, medium-risk transactions are now rejected with reason "external-verification-unavailable" — making the failures visible in the Grafana error dashboard. New Prometheus metrics track outbound call status and latency per provider. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Servlet filter returns 503 on ~30% of requests during the :10 and :40 minute windows (2-min duration each), matching the sim client error spike pattern. Skips /actuator endpoints. Configurable via error-spike.* properties; enabled by default. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Deploys Promtail on every node to tail pod logs from the banking-app namespace (excluding sim-client noise) and ship to Loki. Adds an "Application Logs — Errors" panel to the error dashboard filtering for ERROR/WARN/Exception/panic lines alongside the existing eBPF traffic panel.
